I have looked at plugins and searched for what I want, but I wasn't able to find anything that fully solves my problem. Here's what I want to do.
I want to provide a URL to a page that is password protected. I want there to be multiple passwords for this page, and once a password has been entered, I want it to be a one-time use password. Once they enter, they'll be able to continue to the next page.
Does this make sense? Thanks in advance for your help.
